[Elecraft] Rerouting the KRX3 AUX Input from the Rear BNC to the KAT3

[richarddw1945 at yahoo.com]

Don,
I have my sub receiver connected to the AUX input, and it still works just fine with diversity receive.  The way you do is connect your receive only antenna to the RX in BNC on the back of the K3,  then run a short piece of coax with male BNC connectors on each in between the RX OUT and the AUX input.  Not sure why this method has not been mentioned in the manual. I have being doing this since I purchased my original K3.  I use either Beverages, or the Hi Z 8 now; but am in the process of erecting a SAL 30 fro Array Solutions.   That will give me three different choices for receive antennas.
Dick, K8ZTT

Sverre,

That task can be accomplished by removing only the top cover.

The angled TMP connector on the subRX is a little difficult to reach 
without tilting the back of the subRX up a bit, but it can be done.
